I shoot with a D700 and D7000. Every time I shoot with the D7000 I get annoyed at having to push the + button several times to get to 100%. Yes, that is one of the main features I would miss on a D600. I REALLY like having it on the D700. Virtually every images looks sharp unless you view it at 100%. And many of my images are impossible to do over. Must get it right while the moment is there.
